My new 8 string baby

I have recently stumbled up a late 50's A-5 Gibson Mandolin. I was at a pawnshop of a friend of mine so he made sure I got it. This is really and incredible mando. It is so different from my 1985 Kentucky M850, at first I wasnt sure about it. But the volume of woody brightness has woven its way to my soul. The nut seems slightly wider. And havent figured out what Im gonna do for a strap. But since I have always played around with Celtic, this is just what I needed. Does anyone know where I might get a tailpiece cover with "Gibson" on it?
